NAVIGABLE VESSEL.

SPECIFCAIION forming part of Letters Patent No. 314,435, dated lidarch 24, 1885.

Application tiled August 1P, 1884. (No model.)

To LEZ whom t may concern:

Be it known that I, RUFUs BAn'rLnr'r CoN DON, of Belfast, in the county of Valdo, of the State of Maine, have invented a new and useful Improvemcn tin Navi gable Vessels; and I do hereby declare the same to be described in the following specitication,and represented in the accompanying drawings, of which- Figure l is a` side View with aportion of the hull broken away; Fig. 2, a transverse section ofthe hull ot a navigable vessel provided with my invention, the nature of which is defined in the claims hereinafter presented.

`In carrying out myinvention I hinge to the hull or its keel, fore and aft thereof, a long and thin pendulous plate or wing, having an arm rigidly socketed in'and extending upward from it into anarrow chamber arranged transversely in the hull and separated by water-tight bulk-heads from the interior or hold-spaces of the hull, abaft and forward of such chamber, the whole being so that when the vessel may be at sea and rolled by the waves the hull will swing laterally more or less independently ofthe said plate or wing, and thereby cause the arm with force to vibrate laterally of and in the hull. In this way power may be generated to operate a pump, or to aid in propelling the vessel, or for any other useful purpose. The said pendulous plate or wing is to be made of metal or some material or materials to cause it, when hinged to a hull, to sink in the water and take a vertical position therein when the hull may be afioat.

In the drawings, the vessels hull is shown at A, the pendulous plate or wing hinged to the keel at B, the transverse chamber at C, the bulk-heads at D D, and the hold-spaces forward and abaft of them at E and F. rlhe plate or wing has at its upper part a socket, a, in it to receive the arm G, projecting p from such wing into the chamber C. On with drawing the arm from the socket, the wing, provided with a rope, Z), attached to it at its lower part, can be turned upward against the bottom of the vessel in case of the hull going into shoal water or before entering port. The wing has other advantages, as it will operate in sonic respects as a centerboard usually does.

I make no claim to the manner of attaching a movable to a stationary keel and of shipping and nnshipping the same by means of bolts and chains, as represented and described in the United States Patent No. 4,016, such movable keel being incapable of vibrating laterally independently of the hull; and, furl. In combination with the hull of a navigable vessel, 4a pendulous plate or wing hinged to the bottom thereof, and. provided with a device or arm extended upward from -it (the said wing) within the huil and free therein, so as to be vibrated by it (the said wing) when the vessel may be at sea and rolled by the waves.

2. The combination of a navigable vessels hull provided with a narrow chamber arranged in and atl'iwartships of its hold, and separated from the rest of the hold. by watertight bulk-heads, with a vibratory or pendu` lous wing hinged to the hull and extended beneath it7 and provided with a device or arm projecting upward from it (the said wing) into the said chamber, so as to be vibrated therein by the said wing when the vessel may be rolling at sea.

3. The combination, with the hull of a navigable vessel, of a plate or wing hinged to. and extending down from its bottom and socketed to receive a device or arm extending from it (the said wing) up within the hold of the vessel and free therein, so as to be capable of being vibrated across it by the wing while the hull may be rolling by the faction of the sea, all substantially as set forth.

4. The combination, with the hull of a navi- 2' A 314 ese' gable vessel, of a pendulous plate or wing extending from it to the deek, or thereatolt, hinged to the bottom thereof, and provided snch rope being for drawing the plate or Wing 1o not only with zt device or arm extended npupward to and iatwise against the'hull, Aas

Ward into a narrow chamber, arranged in the specified. A 5 11u11 athwartships thereof and adapted to ztii RUFUS BARTLETT GONDON.
